A 2.865 g sample of Iron (III) Chloride hydrate FeCl3 xH2O was heated at 150°C until a constant mass was achieved (assume all waters have been removed). The mass after heating
was 1.719 g Determine the formula of the hydrate (20 pts)
PLEASE HELP ASAP

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
